If you have never been to our meetings, then check out our last and 11th International Conference on the Scientific and Clinical Applications of Magnetic Carriers that took place in Vancouver, Canada from May 31 - June 4, 2016. Details can be seen here. Especially the special issue of JMMM which was just published is worth checking out.

Combination of MPI and MFH

December 08, 2017

Steve Conolly and his group together with Carlos Rinaldi and his group have just published an interesting article about combining magnetic fluid hyperthermia (MFH) and magnetic particle imaging (MPI). The physics germane to and exploited by MPI and MFH are similar, and the same magnetic particles can be used effectively for both. Consequently, the method of signal localization through the use of gradient fields in MPI can also be used to spatially localize MFH, allowing for spatially selective heating deep in the body and generally providing greater control and flexibility in MFH. Furthermore, MPI and MFH may be integrated together in a single device for simultaneous MPI-MFH and seamless switching between imaging and therapeutic modes.

The authors show simulation and experimental work quantifying the extent of spatial localization of MFH using MPI systems. They report the first combined MPI-MFH system and demonstrate on-demand selective heating of nanoparticle samples separated by only 3 mm (up to 0.4 °C per second heating rates and 150 W/g SAR deposition). They also show experimental data for MPI performed at a typical MFH frequency and show preliminary simultaneous MPI-MFH experimental data.

Iron-Oxide Nanoparticle-Based Magnetic Resonance Contrast Agents

December 02, 2017

If you ever needed to know all about magnetic nanoparticles as MRI contrast agents, then you have it now all in one place. A large group of authors just published a comprehensive review of this field as chapter 4 of of the book "New Developments in NMR No. 13, Contrast Agents for MRI: Experimental Methods", Edited by Valerie C. Pierre and Matthew J. Allen, The Royal Society of Chemistry 2018.

If you can't find it in your library, then please contact Ladislau Vekas, he can help you out.

Fast Magnetic Data Storage

October 15, 2017

Magnetic data storage has long been considered too slow for use in the working memories of computers. Researchers at ETH have now investigated a technique by which magnetic data writing can be done considerably faster and using less energy. Instead of using a current-carrying coil producing a magnetic field to change the direction of magnetization they used an electric current passing through a specially coated semiconductor film. They found that the magnetization inversion happened in less than one nanosecond – considerably faster than in other recently studied techniques. In a first step, the researchers would now like to optimize their materials in order to make the inversion work even faster and at smaller currents.

Frontiers in Biomagnetic Particles Meeting 2017 - Excellent as Always!

October 13, 2017

The 2017 meeting in Asheville, NC, was a great success. This would not be possible without the outstanding talks, posters, and discussions that you can go and check out in the attached abstract booklet here. But it also would not be possible without the energy of the organizers, Jennifer Andrew, Mark Bolding, Thompson Mefford, to again find a great meeting location, excellent invited speakers, and allow for pleasant information exchange and a chance for a good time together. Thank you all!

Successful 5th Colloquium of the DFG Priority Program 1681

October 09, 2017

The 5th Colloquium of the DFG Priority Program 1681: Field controlled particle matrix interactions: synthesis multi-scale modelling and application of magnetic- hybrid materials was held in the Bavarian cloister Benediktbeuern from September 27-29, 2017. This colloquium is part of a special program of the German Research Foundation (DFG), that started in January 2014 and is focused on novel magnetic hybrid materials research. The research ranges from magnetic material production to technical and medical applications and includes modelling of field dependent interaction with different matrices. The large program benefits from the cross-specialization collaboration of chemists, physicist, engineers, biologists, and medics.

Almost 4 years after the start of the program, 86 scientists from each of the 31 projects in the program presented their most recent research findings in scientific talks and posters in the atmosphere of very history-charged walls. The highlight of the annual three-day meeting was, as always, a hiking tour in the mountains that culminates in scientific presentations being given in an alpine hut without any projection equipment. This year, the selected two speakers presented their recently finished dissertations on “Ferrogel actuators for bioapplications” (Emilia Wisotzki, Leipzig) and on “Particle motion investigation by Mössbauer spectroscopy” (Joachim Landers, Duisburg-Essen).

The next colloquium will take place at the end of September 2018, at which time 5 of the 6 years  of the grant period will have elapsed. Planning future research in joint projects will then be in everybody's mind. For more information about this large German grant program, check out:

The Albus Award 2017 Goes to Anna Roig from ICMAB-CSIC

September 06, 2017

Congratulations to Prof. Anna Roig from the Group of Nanoparticles and Nanocomposites, Institut de Ciencia de Materials de Barcelona (ICMAB-CSIC) for obtaining and Albus Grifols Scientific Award.

The Albus Program is an annual international award focused on innovative ideas related to albumin and its role as a therapeutic product. The Program offers two awards of 50,000 € each year. The proposals are assessed by an independent review committee formed by world-wide recognized experts. 
Anna’s “Albumin-iron oxide nanocages” project gets inspiration from the apoferritin nanoconstructs. It aims at investigating if albumin nanocages, consisting of a few units of albumin self-assembled and self-standing, can be formed by using inorganic iron oxide nanoparticles as semi-sacrificial templates. The albumin nanocages could then find application as a nanomedicinal product for imaging and drug delivery.
The winners will be given their Awards at a Ceremony that will take place on October 3rd, 2017 in Barcelona.

Magnetic Microcubes Dance in Magnetic Field

September 03, 2017

A team of researchers including Koohee Han and Orlin D. Velev of North Carolina State University made polymer cubes with 10-µm-long edges and selectively coated one face of each cube with a 100-nm-thick film of cobalt, which can be magnetized. Then they formed aqueous suspensions of the microcubes and showed that by controlling the way magnetic fields were applied to the suspensions, including switching the fields on and off and superimposing fields from multiple electromagnets, the cubes could be made to spontaneously and reversibly assemble in a variety of shapes and patterns (Sci. Adv. 2017, DOI: 10.1126/sciadv.1701108). In some cases, the cubes reversibly switched between a linear chain and ringlike configuration. In others, the cubes underwent complex folding and unfolding.

Adsorbing nominal amounts of magnetite nanoparticles onto the surface of stiff, anisotropic ceramic particles like alumina enables the fast, parallel control of inorganic architectures with weak, scalable magnetic fields. This ultra-high magnetic response has been exploited to produce complex filler architectures in a new family of advanced composites. For more info, contact Randall Erb. To see the movie, click here.
